Request: Environment variable for relative directory about vscode-runonsave

[ehoogeveen-medweb]

Visual Studio Code appears to use ${relativeFileDirname} for this. It doesn't seem to be exposed by Run on Save at the moment though.

FWIW, I managed to work around this limitation with a batch file. It looks something like this:

setlocal enabledelayedexpansion
set "WorkspaceFolder=%~1"
set "FileDirname=%~2"
set "FileBasename=%~3"
set "FileExtname=%~4"
call :strLen WorkspaceFolder length
set /A "length+=1"
set "RelativeDirname=!FileDirname:~%length%!"
rem Do other stuff.
endlocal
exit /b

:strLen
setlocal enabledelayedexpansion
if "!%1!" == "" (
	set /A "len=0"
	goto :strLen_End
)
:strLen_Loop
if not "!%1:~%len%,1!" == "" (
	set /A "len+=1" & goto :strLen_Loop
)
:strLen_End
endlocal & set %2=%len%
exit /b

I have a very similar problem and ${relativeFileDirname} would help me out as well

My workaround for now us to use dirname dist/${relativeFile}:

    "emeraldwalk.runonsave": {
        "commands": [
            {
                "match": "\\.js$",
                "cmd": "npx babel ${relativeFile} --out-dir `dirname dist/${relativeFile}` --source-type script --source-maps --minified"
            }
        ]
    },

FWIW, I eventually switched from using a batch command to a PowerShell script, which is a bit less awkward (with commandlets like Split-Path). Of course, I then found myself having to get it working on Linux as well and ended up writing a dispatcher script based on https://nastytester.com/posts/script-that-works-in-windows-and-linux.html (so I'm back to using a batch command for at least part of the process).
